Given numbers are 209,143,390,863

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 209,143,390,863 is 70343130.

Find LCM of 209,143,390,863 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

11 x 13 x 19 x 1 x 30 x 863 = 70343130

Therefore, the lowest common multiple of 209,143,390,863 is 70343130.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

209 x 143 x 390 x 863 = 10059067590

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

209 : 1, 11, 19, 209

143 : 1, 11, 13, 143

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

863 : 1, 863

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 209,143,390,863, is 1.

Now, the common factors can be found like this.

209:11x 19

143:11x 13

390:2x 3x 5x 13

863:863

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

11x 13 = 143

Therefore, the value for common factors is 143.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 10059067590/(1x143)

LCM = 10059067590/143

LCM = 70343130

Thus, we can understand that the LCM of 209,143,390,863 is 70343130.
